FIT AND SIZING

BONTRAGER FIT GUIDES

Cycling garments are designed to provide function and performance, but they need to fit well to work well. Since not all apparel fits the same, reference our sizing guides below to see how Bontrager apparel and accessories are intended to fit, and find the perfect size and cut for your riding needs.

MEN'S APPAREL SIZING

Bontrager garment fit is based on an athletic build, and follows true sizing. Reference the apparel size chart to identify your size, then see the item's fit profile to understand how the silhouette will move with your body.

MEN'S APPAREL

Measurements on the sizing chart reflect the actual measurements of the body’s circumference (not product’s measurements). Use a cloth measuring tape to measure your body. All measurements should be taken while standing up straight with feet shoulder width apart. For maximum accuracy, take measurements next to skin.

1CHEST

Measure around the fullest part of your chest under your armpits with your arms relaxed at sides. Keep the measuring tape parallel to the ground.

2WAIST

Measure around the natural waist, which falls at the natural curve of the body--the indentation between the hips and the ribcage. The measuring tape should be close to the body but not snug.

3HIPS

Wrap measuring tape around the fullest part of the hips and buttocks. Keep the measuring tape parallel to the ground.

BONTRAGER SHOE SIZING

The Size Conversion Chart below shows how Bontrager's sizing compares to other common sizing scales. However, because the fit of Bontrager cycling shoes is optimized for on-bike comfort and performance, your Bontrager shoe size may be different than that of your street shoe or athletic shoe sizing. For best results, visit your local Bontrager shoe retailer.

The chart below also includes a foot-length conversion scale (in both inches and cm). Follow the steps to measure your foot length correctly and then consult the conversion chart to determine your Bontrager shoe size.

DETERMINING YOUR BONTRAGER SHOE SIZE

Don't have a Brannock device at home? Not to worry, follow the instructions below for at-home sizing or stop by your local Trek retailer to be properly measured.

STEP 1

To measure your feet, start by wearing socks you typically ride in and lay a blank piece of paper on a hard, smooth surface.

STEP 2

While standing, distribute weight evenly and have someone trace each foot with a pencil taking extra care around the toes and heal areas.

STEP 3

If you are working alone, sit down on a chair and lean forward to shift more weight onto the foot you are going to trace.

STEP 4

On your outline, measure the distance from the heel line to your longest toe line and cross-reference with our sizing chart above. If your feet are different lengths, use the longer of the two measurements.
